2016-3-1  Copper can be effectively separated from nickel over the pH range studied. The IL extracts preferentially iron over copper and the highest separation factor β Fe/Cu was 3246 at pH 2.4. The extraction rate of metal ions from a synthetic solution containing copper with other metal impurities was in the order of Fe>Zn>Cu>Cd>Co>Ni.

Kinetics of copper extraction from copper smelting

2020-6-15  1. Introduction. Copper is an indispensable basic raw material for modern industry, however, the grade of copper ore is relatively low in China for the reason that the copper mines are dominated by lean ore, associated ore, and symbiotic ore, especially in the process of smelting it is necessary to add fluxes such as calcium oxide and silica, thus producing a large amount of copper smelting

Copper: Occurrence, principles of extraction,

The chief ore of copper is copper pyrite. It yields nearly 76% of the world production of copper. Extraction from copper pyrites. Extraction of copper from copper pyrites involves the following steps. 1. Crushing and concentration. The ore is crushed and then concentrated by froth-floatation process. 2. Roasting.
